I have a circuit to determine its Q factor. I have the final answer, however i need to understand the derivation part.


I tried to determine the overall impedance at its parallel end but i cant get the answer.. or even illustrating they r all parallel..

Thks.. for the help!!!

the circuit and the q factor answer is at the attached picture

 

Have a look here:

The stored energy is the energy in the inductors/capacitors and the lost energy is the energy dissipated by the resistors.
